' Be it known that I, Grocer: F. Rose, a citizen of the United States, residing in the city of New York, borough of Manhattan.

county and State of New York, have inventcd certain new and useful Type-Writers, of which the follow ng is a specification.

This invention is a typewriter, and it perrains more articular-1y to the key action of a front stri (e machine.

The ob ects in view are, first, to accelerate the upward movement of the type-har,whereby the stroke is quickened, the force of the impact is increased, the efi'ort on the part of the operator is lessened, and the rebound of the type bar from the platen is utilized, in a measure, to return the components of the key action to. normal positions; second, to facilitate the assemblage of the parts and to minimize the adjustment required in securing alinement of the type impressions, and, thirdly, to secure economy in' the manufacture of the parts.

In one embodiment of my new key action, the type bar is provided with a. heel and with a plurality of notches. With said type bar coiiperates a movable member formedwith a notch or opening which produces a 1 prong and a hook, said prong being sorelated to the heel that it will tend to swing the type bar upwardly, whereas the hook;

precludes separation ofthe movable member from the heel of the type bar and tends, a lso, to return sa d type bar back to normal p031 t'ion following the rebound from the platen..-

Said movable member is, preferal'ily, pivoted. separately from the pivot of the typebar, and said pivoted member connected by a link to the key lever and it engages directly with a part of the pivoted type her, said parts acting, to compound the leverage, whereby the stroke of the type bar relatively to the range of movement of the key-lever is greatly magnified, and the type bar asit approaches a platen is accelerated, this last mentioned fiflnction being secured by thecompound leverage referred to and, also, by reason of contacting cam surfaces on the prong of the pivoted member and the heel oi the pivoted type bar.

lhe invention embodies, also, a bracket adapted to be fastened in position on the segment by a sorew and to have its position determined accurately at the time it is assemhledhy centering devices. The securing screws and the centering pins for a p1ural- Specification of Letters Patent.

ports the pivoted type bar and the pivoted member or lever; and, furthermore, to construct said bracket in an integral piece, one

sheet metal and bent or pressed into the re quired shape and size.

Another part of the invention is a s pport for the key lever, said support be ng provided with a slot whereh it may he. placed in position on a rail o themachine frame so as to be held in said position by frictional engagement therewith. With said support cooperates a. centering stud adapted to enter the support and determine accurately its position on the rail, said stud operating, also, to steady the support on the rail and to preclude accidental displacement thereon, and separation therefrom. Y

Other parts of the invention will be set forth in the detailed description hereinafter -andl-not as defining the limits of the invention. y

Fig. 3 is a detached view in side "elevation of the actuating lever. Fig. 4- is a detailperspective view of the bracket adapted to c'arry the pivots of the type bar and its actuating lever, respectively. Fig.1) is a plan view of the blank from which the supporting bar of Figf i is adapted to be produced. Fig. 6 is a detail plan view showing a part of the machine frame and the means for supporting the key lever thereon.

centering pins fora series of brackets adapted to support a like number of type bars and the actuating levers therefor.-

The supporting frame for-the key action Fig." 7 is a detail perspective view of the parts. shown in Fig. (3, the key lever being omitted.

may be of any suitable or preferred vconstruction, but as this frame IS an immaterial part of the invention, I have thought it necemployed for the several perforated at c f'the lu essary only to show the se ment at A and a supporting rail at B. he segment is similar to the general form of segments em ploy-ed in front strike machines, and to said segment is attached a supporting bracket for each type of the series employed in the construction of the key actions." For the sake of clearness, I have shown onlyione key action .in the drawings, stood that duplicates of these key actions are type characters, numerals, and other printing characters.

The hracketwhich I prefer to use is shown in detailin Figs. 4 and 5 of the drawings, and is represented, also, portin the type bar and its. actuating le-' yer. aid bracket is indicated in its entirety by the referenceis composed, preferably, said bracket being bent from a single piece blank, C, of the form shown in Fig. 5. Said blank consists of a stem,

0 wings (fears a, and a lug, 0 The wings and ears are :0, respectively.

The blank is folded or doubled upon itself along the middle line of stem, 0, thus bringing the Wings, 0, into parallel relation to each other, and likewise bringing the ears, 0, into parallel relation to each other. The

lug, c extends upwardly from one wing1 of the bracket, as shown in Figs. 1, 4 an and this lug is adapted, in certain of the brackets, to serve as'a guide for the type bar in the swinging movement thereof. When the brackets are sitions, as toward the serve asjside supports for to reduce the frictionalengagement between and the swinging type bar, I'prefer to'ske etom'ze each lug, as shown, to mimpath of an edge of segment, the closed is, provided with a miie the frictional with the metal-composing the lug. Furthermore, each bracket, or'its lug, 0 may be, or

ward swinging movement of the type her, said stop being shown in Figs. 1 and 5 in the form of a pin, (3, the latter being in the the type bar. It is preferred bracket to the segment by a single screw, D, and for this purpose stem, 0, of the bracket is rovided with a threaded aperture, d. n assembling the bracket on the side of the doubled bracket isplaced against the inner face of the segment so that the threaded aperture, 11, of said bracket will register or aline with a smooth walled opening, d provided in the segment, after which screw, D, is insorted in said .opening, d, and by rotating the screw 1ts threads are caused to engage .se ent."

' or the purpose of assemblin the brackets quickly and accurately wit reference to thesegment, I provide the segment with firmly against the centering holes, e, and the bracket with similar centering holes, e, whereby the bracket may be placed in position for the holes, e, 'e',

retained in position by inserting a centering pin, E, into said re 'sterm holes.

By reference to ig. 8 it will be. noted that the centering pins E for the series of brackets are arranged onthe segment in an arc of a circle whose center is the printing goint for the type bars; and that the screws employed to fasten the bracketsfixedly in position are also in an arc of a circle whose centeris the printing point,'the are for the screws D being concentric to thearc for the centering-pins E. Accordingly, the holes 6 d in the se out for the reception of the center pins and screws D respectively are each arran concentric arcs of circ es whose commoncenf ter is the printing point; and, further, the screw'D and the pin E for each bracket are located in the same radius of such circles.

When the wings, c, and the lugs,c', are folded into parallel relation in the manner heretofore described, the holes, a, are

0', are caused to register, whereby pivot pins, f, 9, may be inserted in the holes for the of pivotally connecting .t bll',- ,and actuatilirg-lever, G, to bracket, C. .By. reference to 1g, 1 of the drawings it 'noted that pin, E, is 10- ca sothat fie type bar can m ftly it, facilljtating' $26 ope 1011'0' m t ars in t e ba iklllatof tlfie iin achiiei ype 'e t or is composed of'a sin 1e iece of metareferably' a single piece s t am ping steel. Asis usual, the type bar is provided with a type head, f, and at the bar is peculiarly constructed, as shown in Figs. 1 and 2, so as to "produce. a heel, f. The heel is provided with a camshaped ed with-a curved edge, It on the o posite'side.

The 1nner edge of finger, g, is shaped to produce acam surface which is adapted to co-act with the cam surface/2,, of heel, f, on the type bar, whereas the hook, g shaped to conform practically to the curved edfge, h,

of said heel, j, for the the purpose 0 keepin the hook in'engagement wlth the curved edge, it, of the type bar heel during the rearw ardl y, or downward swinging movement thereof, whereby the' hook operates to retain actuating lever, G, in engagement with the type bar when the latter is operated byswinging it upwardly and y and forwardly.

ll (-csi nates a key lever composed, preferably, o a single piece stamping of pressed steel, although the particular material of the le er is not essential. Said lever is pro vided at one end with an arm, 2', extending at an angle from the body portion of the lever, said arm formin practically a' bell crank lever.- The key lever is operatively connected with actuating lever, (i, by an. in-- tcrmcdiate link, I. TlllS link is practically a spring, forthe reason that it is composed of wire-or ribbon steel, bent or looped upon itself (memmore times so as to form a coil or coils, 2", intermediate the ends of said link. One end portion of the link is pivotally connected, as at i, to the u )standing free end of arm, 6, of key lever, ll, whereas the other end of the link is connected at i (3 and 7. The members of the foldedplate are provided with openings, j, to receive pivot pin, 9', and said bracket, J, is provided with notches, in, in the folded members of the plate composing the bracket. Said notches are positioned close to the apertures,

j, and they extend through the lower ed 'e of bracket, J, whereby the bracket may he slipped into position on the supporting rail,

B. For the purpose of determining the position of each key lever bracket, J, said rail, .13, is provided with an upstanding center pin, 7.1, the latter being adapted to enter the space of the bracket at the folded edge thereof when said bracket is fitted into frictional engagement with 'rail, B, by pressing the notched part, is, of thebracket lnto position over sai rail. It is preferred to make the center pin, is, of angular form in cross section, the shape being preferably square,

fact that by pivoting the key lever independcntly of the type bar, and by employing the pivoted actuating lever intermediate the pivot of the type bar and the fulcrum 0f the lever, the desired quick action on the type bar, coupled with a minimum depression of the key lever,'1s secured. l urthermore, the

cooperating cam surfaccs'ot' finger, g, on

the actuating lever, G, and on the edge, It,

of the type bar heel secures the im 'iortant function of accelerating the upward and rearward stroke of the type bar, for the reasou that the forward movement of the lever, (Jr, causes the cam face of finger, g, to so act on the cam shaped edge, h, of heel, f that the quickest part of the movement of type bar, F, is the'last part of the stroke of said type bar as it approaches the platen. The effective stroke of type bar, F, is arrested by stop, d, so as to preclude the heel, P, from passing out of engagement with prong, g, of actuating member, (l. The rebound of type bar after it strikes the platen and the. particular relation oi? the parts comprised in the action, returns the type bar quickly to its normal horizontal position. The employment of springlink, I, intermc diatc the actuating lever andthe key lever tends to rcduccthe shock to the linger of the operator during rapid operation of the machine, said spring link yielding at its bent.

or looped portion when the key lever is depressed, mrticularly when it is struck with considerable force, but at th same time said link imparts the proper o oration to the actuating lever to throw thetypc upwardly against the platen.

The action is rapid and cllicicnt in operation, and it is not liableto get out of order. The parts may be assembled quickly and accurately, and by reason of their construction, the key action is economical to manufacture. The several parts are assembled accuratelyand quickly, which is an impor tant construction in theeconomical manu facture of typewriters.
